Objective: The aim of this study is to evaluate the acute and long-term outcomes of ostial stentings among bare-metal stents (BMS), sirolimus-eluting stents, and paclitaxel-eluting stents.
Materials and methods: According to the CAPTAIN (Cardiovascular Atherosclerosis and Percutaneous TrAnsluminal INterventions) registry, from November 1995 to June 2011, 420 patients with ostial lesions were treated using BMS implantations (243 patients with 247 lesions), CYPHER implantations (77 patients with 77 lesions), or TAXUS implantations (100 patients with 104 lesions).
Result: Compared with the CYPHER and TAXUS groups, the BMS group had larger late loss (0.29±0.53, 0.64±0.78, and 1.30±0.79 mm, respectively, P=0.006) and restenosis rate (6, 8, and 33%, respectively, P<0.001). During the long-term follow-up, the BMS group had higher target lesion revascularization than the CYPHER and TAXUS groups (17, 4, and 6%, respectively, P=0.002). The cardiac event-free survival rate, as determined by the Kaplan–Meier analysis, was also lower in the BMS group than in the CYPHER and TAXUS groups (55, 86, and 76%, respectively, P<0.001).
Conclusion: Intracoronary stenting with drug-eluting stent for ostial lesions was associated with lower angiographic restenosis and late loss, and a more favorable long-term clinical outcome than BMS.
